Entry price

When back testing only ohlc data is available, not tick, correct?

1. In the strategy analyzer - backtest panel does setting does setting the Data series Type to Tick or Minute make any difference?

2. Do the generic entries like EnterLong() enter at the open of the new bar?

Hello,

This is correct if you are backtesting on a minute or above time frame. Essentially the backtesting runs on the time frame bars that you load. If you load 15 minute bars it runs on the OHLC of each 15 minute bar. Also yes all actions are taken on the open price of the next bar after the conditions are true.

However if you want to have your backtest run tick by tick you would need to do whats known as adding intrabar granularity and then add in a tick based time fame and submit our orders to this time frame. I would recommend using as large of a tick value you feel comftorable here to speed up the backtesting process. Please see this post on how to do this.

Let me know if I can be of further assistance.

Hold on.

I understand about intra-bar garnularity but I thought tick trading was simply not available in a backtest, ie a 1 min ohlc was all you could get.

Hello,

If you can download tick data from your data feed provider you can absolutly back test on it. You can backtest 1 tick chart if you wanted, would take a long time to run such a backtest but it is possible.

Let me know if I can be of further assistance.
